PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 466,858, dated January12, 1892.

Application filed September 5, 1891. Serial No. 404,820. (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. VRIGHT, a citizen of the United States,residing at New York, in the county and State of New York,

have invented certain new and useful Improvements inPrinting-Telegraphs, of which the following is a specification,reference being had to the drawings accompanying and forming a part ofthe same.

This invention relates to printing-telegraph receiving-instruments, andcomprises certain new and useful improvements therein, which, whileapplicable generally to instruments of this kind, are more especiallydesigned for I 5 use in that particular class of receivers which printthe letters and characters in columns or successive rows.

The main object of the invention is to relieve the electromagnets whichare operated by or connected with the main line of as much u load orwork as possible, which object is accomplished by the use of a suitablemotive power independent of the magnets for effecting the mechanicaloperation of the several parts of the printing and feed mechanism and byutilizing the electrdmagnets merely for releasing, arresting, andgenerally for controlling the action or operation of the said motivepower.

The mechanism as a whole involves the several instrumentalitiesheretofore employed in devices of this character-that is to say, theproper electro-magnets -t0gether With devices for rotating thetype-wheelto bring the proper characters thereon to the printingposition for impressing or printing the characters and for effecting theproper feed movements for letter and line spacing; but thedistinguishing features of the present invention are in the novelcharacter of these instrumentalities. The typewvheel employed has fourrows or series of characters, and is combined with means for raising orlowering the same for the proper alignment of any one of such rows orseries. The said type-wheel is, moreover, constructed to oscillate andthereby print or impress the character on or in the paper. Incombination with the type-Wheel and the feed devices is a power-drivenshaft adapted to operate the same in proper order or succession throughthe instrumentality of cams or similar devices, and various other noveldetails of construction are present, which will be described more fullyherein by the aid of the drawings, and more particularly indicated inthe claims.

In the drawings, which illustrate the construction of the completemachine, Figure l is a general top plan view of the principal operativeparts of the machine. Fig. 2 is a similar plan view, in which, forgreater clearness, all of the magnets but one and certain of the upperparts of the apparatus are omitted. Fig. 3 is an end view of theinstrument inelevation. Fig. 4 is a detail of the typewheel escapement.Fig. 5 isa vertical crosssection of the instrument. Fig. 6 is anenlarged sectional detail of the type-wheel shaft and its bearings. Fig.7 is an enlarged detail of a device forming part of the letter-feed 7omechanism. Fig. 8 is a side elevation proj ection of the releasingdevice shown in broken section in Fig. 5 and from the direction of Viewindicated by the arrow in the latter figure. Fig. 9 is a front elevationand part section of the instrument. Figs. 10, 11, and

12 are details of mechanism detached from the instrument, the nature ofwhich will be hereinafter pointed out. Fig. 13 is an elevation of partof the machine illustrating the action of the mechanism for raising andlowering the type-Wheel. Fig. 1-1 is a part of the same detached.

The various parts of the instrument are supported by a base A, sideplates A A, and suitable cross bars or braces; but the specificconstruction and arrangement of the said parts with reference to this orany other proper means of support is largely immaterial.

The main or signaling line includes three electro-magnets-one asensitive magnet B, that responds to the shortest impulses of current,whether weak or strong, and which is used in connection with thetype-wheel escapement; another a magnet (J, somewhat 5 sluggish in itsaction and not, therefore, affected by a veryshort impulse ofcurrent,but sensitive to any prolonged impulse and which is used as arelay-magnet in connection with the controlling-magnet M for the motivepower, and the third a magnet D, the function of which is to controlcertain devices for varying the elevation of the type-wheel and whichrequires for its operation a stronger current than is necessary foreither of the others.

llfechantsrn for rotattng the type-wheel t present any desired characterof a given row to the paper tn the printing posttion.-A" is athree-cornered horizontal shaft, Figs. 1, 5, and 9, with bearings atopposite sides of the instrument. An extension a of this shaft is round,and its pointed end has a bearing in the end of the escapement-shaft a.This shaft is connected by friction with a pulley a which is constantlyrotated by an independent motor. The tendency to rotation which is thusimparted to the escapementshaft a is controlled by the armature Z) ofthe magnet B, acting as a pawl and oscillating between the tworatchet-wheels 1). Thus the shaft a may be brought to any desiredposition corresponding to a given letter by send- 1 ing through themagnet B the proper number of alternations orimpulses of current. In theshaft a is set a stud or beveled projection 11, and when the said shafthas been brought to the desired position a sleeve B on the extension a,that is formed as a double cam at its end and which moves longitudinallyon the shaft a but turns with it, is shifted by a lever B, engaging withit, into engagement with the stud I). shaft A is thereby turned in oneor the other direction through an arc of greater or less extent,according to the relative positions of the cam-sleeve and stud 1)"before engagement. This rotary movement of the shaft A is imparted tothe type-wheel by bevel gear-wheels c 0, one of which slides along theshaft A, while the other is connected with the vertical type-wheelspindle, as hereinafter set forth. In this way by giving to the end ofthe camsleeve 13 a proper form the type-wheel may be turned in onedirection or the other from any given point to presenta selectedcharacter for printing and is never turned more than a half-revolution.

The type-wheet ancltts carriage.'lhe typewheel proper G is a lightcylinder, preferably of such material as aluminiu m,and isprovided withfour rowsof characters,generally made of rubber or rubber-faced type andindicated by the numerals l 2 3 4:. This cylinder is fixed to a verticalspindle C",the lower end of which passes through a slotted plate over astep D, fitted to and adapted to be moved freely along a guide rail orbar-D" by the transverse movementof thespindleG. The spindleOpassesthrough avertical sleeve or cylinder d, which is capable of rotationabout its longitudinal axis. The bearings for the sleeve (Z are at theends in plates at, which are secured to the type-wheel carriage, theframe of which is designated by d" rt. Said carriage is pro- -vided withrollers e, that travel on guide-bars The spindle 0 passes freelythrough- The cam-sleeve and with it the a free movement of limitedextent vertically through said sleeve, and,being of smaller diameterthan the bore of the sleeve, is also capable of oscillation within saidsleeve in a given vertical plane, the center of oscillation beingtheball-joint. The elevation of the spindle or its vertical position withreference to the sleeve obviously depends upon the position of the stepDand bar D", by which its lower end is supported. A bifurcated lever Fis pivoted to the type-wheel carriage, as shown at F in Fig. 13,and theend of this lever extends downward into the path of a swinging frame,which depresses it when an impression is to be made. The lever F carriesa light spring g, that bears upon the typewheel carriage and retractsthe lever after each impression. The said lever is also provided with atooth g, which, when the lever is depressed, enters a recess or slot ina cylinder g on the lower part'of the spindle C and locks the spindleagainst any rotary or lost movement. This perforated cylinder or cage gis made to correspond with the typewheel and has four rows of holes, sothat when the lever F is depressed the tooth g will enter that holewhich corresponds to the character to be impressed or printed. Thedepression of the lever F has also the effect of throwing the type-wheelover against the paper which is carried on a roller G and printing theletter that is presented at the printing-point. On the retraction of thelever F, the spindle O and the type-wheel thereon adjust themselves atonce to their normal position. A small flat spring h is placed on thestep D, and being bent by the displacement of the end of the spindlefrom the center of the step, exerts sufficient force to return the samewhen released from engagement with the lever F.

The feed mechanism for the type-wheel carrtage.G G are two rack-barsthat extend across the instrument parallel to the path of the type-wheelcarriage. One of said bars, as G, is stationary, while the other, beingsupported by the pins h h, passing through slots h, Fig. 9, is capableof limited longitudinal movement equal to the space between two teeth.This raclcbar is arranged, as will be hereinafter described, to bereciprocated through such space every time that the magnet 0 isenergized. Between arms H, depending from the type-carriage (1'', Figs.1, 5,'and 7, are pivoted two pawls 2' t, which are in engagement withthe two racks G G, respectively. The reciprocation of the bar G causes,through the instruinentality of these pawls, the type-wheel carriage toadvance through the space of one tooth for each to-and-fro I V i ofengagement with the racks.

movement of the said bar G, and in this way the letter-spacing or feedis accomplished.

Between the two pawls i and i and with bear The upper end j of thislever carries a light pivoted bar 7r, that extends at right angles andover both pawls i i, as shown in Figs. 1 and' ings in the arms H is apivoted lever l.

9. The bar has sufficient range of oscillaremoved from the path of thepawls.

An armj of the lever 1 extends under the pawl i", and when the lever 1'is turned about its pivot the oscillating bar 7c is carried away fromthe pawls i i, as

shown in Fig. 7, and the latter are lifted out is then free and isreturned by a cord is, at-

spring-barrel 7c". The lever l is turned by a bar H, carried by swingingarms H and extending under the lower end of the lever 1, parallel to itsline of travel. hen the bar H is ,raised by mechanism hereinafterdescribed, it is engaged and retained in an elevated position by-aspring-hook I, attached to .the side plate of the instrument. It isdisengaged by the carriage itself, which on reaching the end of itscourse strikes the spring or a-pin- J, connected therewith, and allowsthe bar H to drop. This action immediately drops the pawls i i intoengagement with the racks G G.

The pciper-feed.lVhenever the ty pe-wheel carriage is thrown back tobegin a line, the paper is fed through a sufficient space for the newline. The paper is taken off from a reel J and carried around theprinting-roll G. ()n

. the shaft of the roll G isa ratchet-wheel Z, with which pawls Zengage. These pawls are operated by a lever K, to which they areconnected by a link Z. When the lever K is raised, a stud K thereonraises the bar ii that releases the pawls on the type-wheel carriage,while at the same time the paper-roll is turned through thespace for aline.

The actuating mechanism.ln printingtelegraph instruments heretofore ithas been usual to impose upon the electro-magnets, either in the main orlocal circuits, a considerable part of the work of printing, feeding,and the like; but the efficiency and capabilities of the apparatus areby such means necessarily impaired. In the present invention, while itis evident that some or all of the several mechanisms hereinbeforedescribed might be operated by electro-magnets, the ob ject sought is tooperate them all mechanically and to employ the magnet or magnets simplyfor purposes of control. The mechanism devised and employed for thispurpose will now be described. A main shaft L is. mounted in the frameand is provided with a The carriage friction-pulley L, which in theoperation of the machine is designed to be constantly rotated by asuitable source of power-as, for example, a small eleotro-magneticmotor. The shaft L is normally locked against rotation by the engagementof a stop L" on the shaft L with the end of the armature-lever m of alocal electro-magnet M, controlled by the relaymagnet G. The said leverm carries, also, a spring-actuated pawl m, limited in its movement by astop in". Then the armature is attracted to the magnet M, the end of itsleverm is withdrawn from the path of the stop L,and the shaft L isturned byits frictional connection with the motor. In order to arrestthe shaft after making one revolution, the

pawl m is used. This pawl is brought into the path of the stop L by themovement of the armature-lever, which releases the latter, and,receiving theimpact of the stop L, it is moved against the force of itsspring until the stop m" is encountered. Then upon the return of thearmature-lever m the stop L slides from the pawl m onto the end of thelever m; When the escapement-wheel b is brought by rapid alternations ofcurrent to the proper position for bringing a given character into theprinting position, the final impulse of current operates the magnetsC'and M and releases the shaft L, permitting the latter to make onerevolution.

The type wheel setting mechanism.The shaft L carries an eccentric Q,upon the periphery of which bears a stud or collar Q on a rocking arm Q,connected by a link R with the pivoted lever B, that connects with thecam-sleeve B. The first effect following the rotation of the shaft L isto force the levers Q, and B" back, and by sliding the camsleeve 13along on its shaft into engagement with the stud b, to turn and set thetypewheel until it presents at the printing-point the characterdetermined by the position of the said stud b".

The impression mechcinism.An eccentric M is also carried by the shaft L,and a roller on the end of an arm M" bears on the periphery of the same.This arm extends from a rock-shaft N, from which is supported by arms na bar N, arranged to encounter the end of the printing-lever F anddepress the same. One of the functions of the shaft L, therefore, is toimpart partial rotation to the rock-shaft N by means of the eccentric M,and thus print or impress one of the characters ,on the type-wheel ateach revolution.

The letter-feed and spacing mechanism. Depending from the movablerack-bar G is a yoke N, between the arms of which is an cecentric O,fixed to the shaft L. By this means the reciprocating movement necessaryfor the feed of the type-wheel carriage is imparted to the rock-bar G byeach revolution of the shaft L.

llfechanism for returning type-wheel carriage and feeding the papenlhefollowing devices are employed to operate the lever K for feeding thepaper and sending the typecarriage home to begin a new line: 0 in; Figs.9 and 12 is a bar extending across the machine. The bar is formed with asaddle O", that fits over the shaft L and carries an anti-frictionroller 0, resting on the periphery Every revolution of the shaft L willtherefore raise One end 1 of the bar 0' passes through a guide-plate 0and enters .an opening or'slot in the lever K. The other end passes j ofan eccentric 0 on the said shaft.

and lower the center of the bar 0'.

(Shown at p in Fig. 5.) through a slot in the side plate A, and spiralsprings 19' p, of which the former is the stronger and more difficult todistend, are

.connected to the bar near its opposite ends and to the bed-plate of theinstrument. If

both ends of the bar are free to move, it

is obvious that the raising and lowering of the center will produce anoscillation of the bar about that end as a center which is held down bythe stronger spring 19, and the leby a spring 7", that keeps the lowerend of the same normally out of the path of movement of the projectingend of the bar 0. Then the paper is to be fed, the escapement-shaft isturned by the proper number of impulses, so that the last or prolongedimpulse brings a pin 0" directly in the path of the upper end of leverq. Hence when the lever P is oscillated the lever q, coming intoengagement with the pin 0"", is turned so that its lower end interceptsthe end of bar 0', preventing the same from rising. The fulcrum of thebar is thus shifted from the opposite end, so that the lever K will beraised, which, as above described, retu rns the type-wh eel carriage andfeeds the paper.

An instrument constructed in the manner above described combines all theelements essential to the operation of a type-wheel with a single row ofcharacters or which has but one vertical position. In the present case,however, it is proposed that the type-wheel shall have four differentpositions, which, for convenience, are designated as the first, or thatwhich has been described, the second, thirc and fourth positions.

I The second position: The electro-magnet D has been described as onerequiring a stronger current for its operation than the magnet O and asbeing connected with the main line. \Vhen a character is to be printedthat requires the type-wheel to be in the second position, the finalcurrent-impulse that is required to turn the type-wheel horizontally forthe proper alignment of the selected char acter thereon is sent fromadditional battery or through less resistance, so that all three of themagnets B, O, and D are energized. The pivoted armature-lever R of themagnet D extends through a slot in the side plate A and carries at itsend a forked extension 8, that embraces a lever R, Figs. 13 and 14. Thelever B" is pivoted to a bracket 5 by a universal joint, so as to becapable of swinging both vertically and horizontally, and its end isprovided with a stud or roller 3'', that rides on the periphery of aneccentric S on shaft L. An arm S is attached to this lever and carries asteadying-roller S", that runs on the under side of the eccentric S.Each revolution of the .shaft L, therefore, causes the leverR" to riseand fall; but the lever being normally disconnected from the other partsof the apparatus no effect is produced thereon. The bar D", upon whichthe step D of the type-wheel spindle travels, is supported by arectangular frame T, supported by guide-rollers 'l" and capable ofmoving freely in a vertical plane. Two pins 7. and 15 are set in oneside of this frame. One of the two pins 15 stands opposite to a hole 6"in the lever B" when the said lever and the frame T are in their normalor lowest position. The

stronger current impulse that is sent to print a character on the secondrow of type open ates the magnet D and shifts the armaturelever B, whichcarries the lever B" with it, causing the pin t on frame T to enter thehole in said lever. In consequence of thus connecting the lever B" andframe T the latter is raised by the eccentric S and the type-wheelbrought to its second position. After the impression is made the frame Tis lowered, and as soon as the magnet D is demagnetized and its armatureretracted the lever B" is disconnected from the frame T.

The third position: When a character is to be printed that is on thethird row on the type-wheel, the latter must first be brought to thethird position by one operation and the character printed by another. Alight bar T is pivoted to the frame T and extends out through a slot inthe side plate A. The end of this bar is connected by a link a, Fig. 13,with a bell-crank lever'u, pivoted to the side plate A and provided witha stop u". Under the bar T" is mounted a lever U, one end of which bearsagainst the under side of the bar, while the other carries ananti-friction roller that rides on the periphery of an eccentric U onthe shaft L. The leverU is oscillated by the rotation of the shaft L andraises and lowers the bar T; but the end of this bar, to which isconnected the link to and bell-crank lever to, being free to move, thebar merely oscillates about its pivotal point on the frame T withoutproducing any effect on the other parts of the apparatus. Theescapement-shaft a, as has been above described, carries the pin r",which is in line with the stud b, and hence never encountered by thecam-sleeve B. To raise the type-wheel to the A plate '10 (shown in Figs.1, 2, and 3) is con- "third position, the escapement-shaft is turneduntil this pin 0"" is brought into the path of the stop it on theoscillating bell-crank lever a. The shaft Lbeing then released by themagnet M, the eccentrics impart the move ments above described to theseveral levers; but since the bell-crank lever to is prevented fromrising, the lever T, instead of swinging and remains so until by aspecial operation it is shifted to another.

Mechanism for restoring typawheel from.

third to first post'zft'on.-The catch 1;" is a small lever, pivoted to astationary support,

and held normally in the path of the bar D".

The engaging end, however, is beveled on the under side, so that as thebar D" rises it forces aside the catch, but when the latter slips underthe bar it prevents its descent.

nected to one end of the catch-lever o", and

. a spiral spring attached to the said plate and the frame of theinstrument, respectively, serves to maintain the catch in its normalposition. A pin 20', set in the plate to, projects through a slot in theside plate A. The le-. ver P, Fig. 3, has pivoted to it a small lever w,the upper end of which is in the plane of the revolution of the pin 0"on the escapement-shaft.

through the plane of its oscillation. If it be desired to shift thetype-wheel from the third to the first position, the escapement is setso that the pin 1*" will encounter the end of lever 00 as the latteroscillates with the lever P.

Vhen this is done, the lever 00 will be turned on its fulcrum and itslower end will force the pin to and plate to forward, thus with drawingcatch 1;" from engagement with the bar D and permitting the latter tofall back to the normal position. It may be observed that while both theraising of the type-wheel to the third position and restoring it to itsnormal position involve a revolution of the shaft L and the consequentoperation of the feeding and printing mechanism, no impression is madeif blanks be left on the typewheel in positions corresponding to thesaid positions of the escapenient-shafhbut the type-wheel will be movedor fed one letter The type-wheel remains normally in the first positionand drops after each impression from the second to the first. to thethird position it remains there, as has A light spring so bears 011 thelever m and maintains its lower end out of e11 gagement with the pinto", which extends WVhen once brought been explained, unless by aspecial operation it is returned to the first. It may be raised from thethird to the fourth position, but after each impression it drops back tothe third in the same Way that it returns from the second to the firstposition.

The fourth position: The lifting of the type-wheel from the third to thefourth position is effected by the magnet D and lever R". When thetype-wheel is in the third position, the elevation of the frame T bringsthe pin i into the position normally occupied by pin 25 with relation tothe lever R. Hence, if the magnet D be energized, the lever B will bebrought into connection with the frame T by the pin i entering the hole25, and the frame and type-wheel will be raised to the fourth position.

With the instrument, of which the essential characteristics are abovedescribed, a suitable transmitter is employed that automaticallycontrols the selection and printing of characters, according to theparticular manipnlation of the same by an operator, so that a high rateof transmission is secured.
